The present work is designed to supply a want which has long 
been felt by those commencing the study of medicine and the 
collateral sciences. 

An acquaintance with the dead languages, or at least with Latin, 
Was formerly, and in some parts of Europe is still, considered 
absolutely necessary for a graduate in medicine as well as in the 
other learned professions. Although in the United States a clas- 
sical education is not made an indispensable condition for conferring 
a medical degree, yet, so long as the great majority of professional 
terms are in Latin, some knowledge of this language may be said 
to be absolutely requisite for the medical student. The fact that 
multitudes of our young men commence the study of medicine 
without any previous acquaintance with Latin or Greek, renders 
it important that the elementary works intended for the use of 
students should be adapted to meet this exigency. 

To supply the want above indicated has been one of the chief 
objects of the present work. In fulfilling this object, the editor 
has aimed, — 

First: to give a full explanation of the etymology of the various 
words defined in the Dictionary. The importance of etymology 
in furnishing, as it generally does, a sure clue to the true sig- 
nification of scientific terms; in limiting and fixing their mean- 
ing, thus guarding against looseness or vagueness of application ; 
and lastly, and not least, in assisting the memory of the learner, 


since, by acquiring a knowledge of a comparatively few elements 
or roots, he is thus enabled to determine the signification of a 
multitude of compound words, — can scarcely be overestimated. It 
is admitted, indeed, that terms not unfrequently occur of which 
it is difficult or impossible to give an entirely satisfactory etymo- 
logy. In a few of the most doubtful cases of this kind, it has been 
deemed best to make no attempt to explain the derivation, since 
an etymology which is purely fanciful or speculative, seems far 
more likely to mislead or perplex than to instruct the student. 
It may be proper to add that, in fulfilling this important part of 
his task, the editor has not been content with merely following 
the generally received authorities in etymology, but has made it 
a rule, in every case of doubt or uncertainty, to examine the sub- 
ject anew, and particularly to consult the best classical and modern 
(foreign) dictionaries upon the point in question. 

Secondly: to give, whenever practicable, a literal translation 
of the various Latin phrases, sentences, etc. occurring in the work: 
such, for example, as Extensor Digitorum Communis, Motor es Ocu- 
lorum, Hydrargyrum cum Cretd, etc. etc. The importance of such 
explanations in giving clear and definite ideas to those who may 
be unacquainted with the Latin tongue, is too obvious to require 
to be enlarged upon. 

For an explanation of some of the most important elements and 
principles of the Latin language, designed chiefly for those who 
have not had the advantage of a classical education, the reader is 
referred to the Appendix, page G60. Connected with, and imme- 
diately following, this portion of the work, will be found rules 
and directions for the writing of Latin prescriptions. 

Another feature in the work, and one which it is hoped will 
prove of great practical importance, is the pronunciation of the 
various terms given in the Dictionary. What correct spelling is 
to the writer, correct pronunciation is to the speaker. If either 
should be wholly neglected, the most perfect language would soon 
become a babel, and fall into utter corruption. Every one who 
takes the trouble to reflect on the subject must be aware that if it 
were not for the constant effort or aim to conform our speech to a 
common standard, the language which we call English would in 
the course of a few years be spoken so differently in different parts 


of the world, as to be with, difficulty understood, and in two or three 
centuries it would, in all probability, become wholly unintelli- 
gible, except to those few who might happen to be familiar with 
the local dialect. He, therefore, who is willing to take the pains 
to speak correctly, not only acquires an accomplishment which 
will raise him in the estimation of all educated men, but he con- 
tributes his portion towards exalting and extending the incalculable 
blessings which language, the great vehicle of thought and know- 
ledge, is capable of conferring on mankind. 

The various terms employed in medicine may be divided into 
two principal classes. The first class consists of those which are 
properly English or have an Anglicized termination, whether de- 
rived from the Saxon, as, Blood, Forearm, Nightmare, Rickets, etc. ; 
from the French, as, Bandage, Viable, etc. ; from the Latin, as, Ab- 
dominal (from abdominalis), Abortion (from abortio), Astringent 
(from astringens), Ferruginous (from ferruginosus), etc.; or from 
the Greek, as, Apoplexy (from anoTtX^ia), Artery (from dpzTjpca), 
Asthmatic (from aadij.aru.dq), etc. 

The second class comprises all such terms as are Latin or 
Latinized Greek, as, Abdomen, Amaurosis, Ammonia, Asthma, 
Cerebrum, Laryngitis, (Esophagus, Sternum, Vertebra, etc. etc. 

The pronunciation of the former class of words is attended with 
no particular difficulty. Those of the second class, however, 
though usually very easy with respect to the accentuation, and 
perfectly uniform as to the sounds of the consonants, present a 
very serious difficulty in regard to the pronunciation of the vowels. 
At the University of Oxford in England, and at Harvard in the 
United States, it is the usage to pronounce all Latin words with 
the English sounds of the vowels: for example, a when long (as 
the second a in ama're, ama'bam, ama'tum) has the same sound 
as our a in fate (never like a in far); long i is pronounced as in 
pine; and so on. But many of the institutions of learning in this 
country have adopted what is termed the " continental" pronuncia- 
tion, according to which, the vowels are pronounced, not after 
the English sound, but according to that of the languages of 
Continental Europe. As, however, there is some diversity re- 
specting the vowel sounds of the different European tongues, the 


Italian, which of all the modern languages is perhaps most nearly- 
related to the Latin, has generally been adopted as the standard. 
According to this system, a should be sounded nearly like a in far, 
e as in there, or like a in fate, i as in marine, or like e in mete, u 
like oo, and y like i, that is, like our e. In some portions of 
our country, particularly in the Middle States, there unfortu- 
nately prevails a third system, consisting of a sort of mixture of 
the other two already described. According to this system, — if 
such it may be called, — the vowel a is sounded as in fast or fat 
(never as in fate); i, when long, is usually pronounced as in pine, 
though sometimes as in marine; all the other vowels being uni- 
formly sounded as in English. The improper diphthong ce, which in 
every other modern language corresponds in sound either exactly 
or very nearly to e* is on this system sounded like our a in fate. 

As may readily be imagined, these three different systems ex- 
isting together in the same country, have had the effect to intro- 
duce almost unlimited confusion into the pronunciation of Latin 
words. Those who aim at correctness or propriety in speaking 
should, we think, adopt either the Oxford pronunciation or the 
continental; and whichever they adopt should be carried out con- 
sistently. It is greatly to be desired, however, that some common 
standard of Latin pronunciation might be fixed upon for the whole 
United States: it would be of immense advantage even were its 
application limited to scientific terms and phrases. 

Under the existing state of things, the editor has not felt justified 
in attempting to lay down any positive rules for the pronunciation 
of the vowels occurring in Latin terms. He has, accordingly, for 
the most part confined his labors in regard to this class of words, to 
marking the accent and syllabication, and to indicating such vowel 
sounds (e.g. short i and short y) as are essentially the same 
whether they are pronounced according to the continental or 

* That is, to the sound of e in the respective languages ; ce in French being 
equivalent to the French e, ce in Spanish to the Spanish e, and so with the 
rest. To sound ce differently from e tends to great confusion, inasmuch as a 
multitude of words are now written almost indifferently with the diphthong 
or the vowel: as, JEclile or Edilc, JEtiology or Etiology, etc. However such 
words may be written, the pronunciation ought, unquestionaVy, to remain 
the same. 


the English mode. The most important point of all is the accent, 
which can, for the most part, be readily ascertained, and, depend- 
ing as it does upon the quantity* ('not on the quality) of the 
vowels, remains the same under all the different systems and in 
all the various tongues of the world. The principal rules for 
Latin accentuation are the following: — 

Eule 1. — In trisyllables or polysyllables, if the penultima be 
long, the accent must fall upon it: as, Abdo'men, Coni'um, Duode- 
num, Porri'go, Scapula'ris, etc. 

Eule 2. — If the penultima be short, the accent must fall on the 
antepenultima : as, Ac'idum, Abdom'inis, An'ima, Assafozt'ida, 
Chimapk'ila, Cimicif'uga, Hydrocephalus, Polycfala, etc. 

Eule 3. — Dissyllables always take the accent on the penultima; 
as, A'cor, Co'ma, Liquor, &c. 

It may be observed that whenever the accent of a Latin word 
falls on the antepenultimate vowel followed immediately by a 
single consonant, the accent is usually placed after the conso- 
nant, and the vowel is made what in English. we term "short." 
(See examples under Eule Second.) Accordingly, we pronounce 
Abdominis — abdom'inis, Assafoztida — assafet'ida, etc., although in 
both of these instances the penultimate syllable is long in Latin.f 
The only important exception to this rule occurs in words having 
u for the antepenultimate vowel; as, Alu'mina, Sulphu'ricus, etc., 
in which case the accent should always be placed before the conso- 
nant, the vowel retaining its full or long sound.J 

It has until recently been the almost universal usage among 

* The quantity is determined chiefly by the usage of the Latin poets, and 
certain recognized rules of derivation. 

f It is very important to bear in mind the essential difference between a 
long vowel in English and a long vowel in Latin or Greek. In the former 
case the word "long" refers to the quality of the vowel, in the latter always 
to the quantity. The pronunciation of a long vowel in Latin or Greek is 
estimated to occupy just twice as much time as is spent in uttering a short 
vowel. In the present work, however, when the term "long" is employed 
in reference to the pronunciation of a word, it is to be understood in the 
English sense, if the contrary be not distinctly stated. 

X The plural of Greek nouns in -oma are, by common usage, excepted : as, 
aro'mata (from aro'ma), not arom'ata. If the penultima be a vowel followed 
immediately by another vowel, the antepenultimate syllable is usually made 
long : as, am-mo / ni-a, ci-ne're-us. 


classical scholars to pronounce the ancient Greek (like the Latinj 
according to the quantity of the vowels ; but within a few years 
some institutions of learning of the highest character, both in 
Europe and in this country, have adopted the modern Greek 
accentuation; that is, they pronounce according to the Greek 
accent, without the slightest reference to quantity. For example, 
aotpia ("wisdom"), and tikixpavov (the "elbow"), formerly called 
so'fe-a and o-le-kra'non, would, according to the new mode, be 
pronounced so-fee'a and o-lek'ra-non. How far this new system 
should affect our pronunciation of Latinized terms derived from 
the Greek may be considered an open question.* 

As already intimated, the • accent is the chief, if not the sole, 
point in Latin pronunciation about which there is no dispute 
among the learned. It has accordingly come to be regarded as 
one of the essential tests by which a finished scholar may be 
known. Our readers need scarcely be reminded that many Latin 
phrases and sentences have become, so to speak, parts of our own 

* While it must be admitted that all, or nearly all, the best English autho- 
rities on classical pronunciation recognize no other principle than quantity 
for the accentuation of this class of words, it may be observed that in Italian 
and Spanish, — languages much more nearly related to the Latin than ours, — 
words and names derived from the Greek almost invariably follow the accentua- 
tion of the original, while those of Latin derivation are as uniformly ac- 
centuated according to the quantity of their Latin primitives. Not only 
is the name Sofia (from the Greek co&a, whence our SopTii'a) pronounced 
so-fee'a (though in Greek the penultima is short), and its derivative filosofia 
("philosophy") fe-h- so-fee'a, but the numerous class of Italian and Spanish 
words ending in -ffrafia (Greek -ypafia), and -logia (Greek -Xoyia) always 
have, like the Greek, the accent on the penultima, although this is invariably 
short in the Greek; as cosmografi'a (cosmography), geografi'a (geography), 
ortografi'a (orthography), &c. ; and analogVa (analogy), filologi'a (philology), 
etc. etc. Insania takes the antepenultimate accent, because the penultima of 
the Latin (insa'nia) is short; while mania, with the same termination, has the 
penultimate accent (ma-nee / a), simply because the Greek (jiavia) is so accented. 
JKir The remark made above, that words in Italian and Spanish derived from 
the Latin follow the Latin quantity, while those from the Greek conform to 
the Greek accentuation, should of course be limited to such as have not become 
materially changed or corrupted. It will be seen that in the examples above 
cited no change has taken place, except substituting/ for 0, whicn does not 
in the slightest degree affect the pronunciation. 


fanguage. He, therefore, who aspires to the character of a correct 
and polished speaker, cannot, without serious danger to his reputa- 
tion, neglect this important branch of orthoepy. It is true that a 
very few words of Latin origin (as Au'ditor, Or'ator, /Sen'ator* etc.) 
have, on becoming Anglicized, without any change in the spelling, 
lost the original penultimate accent. But the large majority of 
Anglicized words retain the classical accentuation, as Acu'men, 
Alb u' men, Aro'ma, Cogno'men, Deed rum, Dicta! tor, Fari'na, Far- 
ra'go, Sori'zon, Sali'va, Specta'tor, etc., all of which have resisted 
the general tendency of our language, which is to throw the 
accent on the antepenultima in such words: indeed, we not unfre- 
quently hear uneducated people say, Ar'oma, Cog'nomen, Sal'iva, 
etc. If, then, Anglicized Latin words, which are in everybody's 
mouth, are generally pronounced according to the original accentu- 
ation, scientific terms ought unquestionably to be always so pro- 
nounced. This principle is, indeed, fully recognized in the accentu- 
ations given in the last edition of our Pharmacopoeia, in which, we 
believe, not a single instance occurs of a Latin name that does not 
conform to the classical pronunciation ; although, if English analogy 
were allowed to have any influence, we should scarcely pronounce 
Coni'um, Mati'co, etc., with the accent on the penultima. 

Gf such Latin words as were used by the ancients, there ia 
generally no difficulty in determining the accentuation. But the 
case is different with respect to Latin terms (consisting chiefly of 
botanical and other scientific names) of modern origin. Among 
these there are a number of which the etymology is obscure or 
uncertain, and the accentuation is, in consequence, more or less 
doubtful. In such cases, the editor has not only sought to avail 
himself of the light which general analogy might shed upon the 
point in question, but he has carefully consulted all the best works 
accessible to him, relating to such subjects. Among these he 
would express his particular obligations to Gray's " Manual of 
Botany," Mayne's "Expository Lexicon," Wittstein's "Etymo- 
logisch-Botanisches Worterbuch," and, above all, to Dunglison's 
" Medical Dictionary," which in relation to these difficult questions 

*Anemo / ne, when used as an English word, is always pronounced anem'one. 


exhibits a degree of accuracy, as well as judgment, unsurpassed, if 
not unequalled, among scientific works of reference. 

Those who take a particular interest in such subjects are re- 
ferred to the "Table of Disputed Pronunciations" (see Appendix, 
pp. 698-9), containing a list of the most important terms occurring 
in medical works, respecting the accentuation of which there is a 
difference among the best orthoepical authorities.* 

Respecting the plan of the Dictionary, it may be observed that 
immediately after the term itself, if this be English, is inserted 
the Latin synonym, then the etymology, both being enclosed in 
brackets. If the term be Latin, it is immediately followed by the 
etymology, enclosed in brackets. (Compare Ablactation, Apoplexy, 
Artery; also, Abdomen, Ablepsia, etc.) The French synonyms of 
important medical terms are also given, excepting such as are 
essentially the same as the English or Latin : for example, Ablacta- 
tion ("ablactation''), Bandage (a "bandage"), Uterus (the "ute- 
rus"), etc.; or such as differ only very slightly, as Apoplexie 
(" apoplexy"), Artere ("artery"), Hepatite ("hepatitis"), OEsophage 
("oesophagus"), etc. As these would, for the most part, be readily 
understood without a dictionary, they have generally been omitted. 
By adopting this plan, the attention of the student is particularly 
directed to those French terms which it is most important for him 
to acquire ; that is, to such as are essentially different from the 
Latin or English, and therefore not likely to be understood unless 
explained. Of this class of words the following examples may 
be given: — -Cozur ("heart"), Clou ("clove"), Cou ("neck"), Main 
("hand"), CEil (" eye"), Poumons ("lungs"), Toux (" cough"), etc. 

A considerable portion of the Appendix is occupied with the 

* In speaking of "authorities" in regard to questions of this kind, we do 
not, of course, allude to those persons, however illustrious, who are merely 
distinguished for their scientific attainments or for their general learning, but 
to sach only as have paid particular attention to the subject of orthoepy. It is 
not to be denied that some, who are justly regarded as ornaments of science, 
either from never having given any attention to such subjects, or from mere 
carelessness, are most untrustworthy guides in all that relates to correctness of 
language, whether written or spoken. They seem to forget that thoughts are 
like jewels: the greater their value, the more important it is that they should 
be well set, that their beauty may be exhibited to the best advantage. 


" Table of Materia Medica," containing the names of all, or nearly- 
all, the medicinal articles of any importance, arranged according 
to their medical properties. Such a classification, it is believed, 
will be found extremely useful, at least to those who have not had 
time or opportunity to make themselves thoroughly acquainted 
with the vast resources of our Materia Medica. 

Besides the articles already mentioned, included in the Ap- 
pendix, it contains a tolerably complete Table of Doses, prepared 
with great care. It also contains a synopsis of the respective 
Nosologies of Cullen and Good. Although at the present time 
neither of these systems is generally followed, both have exerted 
great influence upon medical nomenclature, and may, therefore, 
justly claim some notice at our hands. It was believed that in no 
other way could an idea be given of them so clearly and so briefly 
as by means of synoptical tables. 

Among the multitude of works which the editor has had occa- 
sion to consult in the preparation of this Dictionary, justice re- 
quires that he should express his great obligations to a few to 
which he is especially indebted. His acknowledgments are pre- 
eminently due to Mayne's " Expository Lexicon" (London, 1860) ; 
a Dictionary of Medicine, original in its plan, and evincing in its 
execution much diligence, learning, and research. He would also 
express his important obligations to Gray's " Structural and Syste- 
matic Botany," and "Manual of Botany," to which he has gene- 
rally had recourse as his chief authorities on all questions relating 
to botanical science. To Hoblyn's "Medical Dictionary" he is 
indebted for the matter of a number of articles, particularly those 
relating to chemistry. The notices of the natural orders of plants 
and animals have mostly been taken from that justly popular 
work, Brande's " Encyclopedia of Science, Literature, and Art." 

Nor can he omit to mention his great and important obligations 
to Wood and Bache's " United States Dispensatory," a work 
which justly ranks among the first of its kind that have ever 
been published in this or any other country. 


a, e, 1, o, u, y, are long, as in fate, mete, pine, note, tube, fly. 

a, e, 1, o, u, % are short, as in fat, met, pin, not, tub, mystic. 

a, e, and 6, are like a, e, and o, except that the sound is less prolonged. 

a, e, are obscure, as in the final syllables of America, icriter, etc. 

g = g hard. 

e is to be sounded like s or ss ; Q and g like// s has the sound of z. 

■eh is to be sounded like k; but ch without any mark should be pronounced as in 
chill or child. 

n, m, and n° are used to represent the French nasal sound, somewhat resembling 
that of ng in long. R (small capital) implies that the r should be trilled: ii denotes 
the sound of the French u; v, that of the French en, similar to the sound of u in 
the English word fur. 

An asterisk (9) afiixed to a word or phrase denotes that it is either Latin or Latin- 
ized Greek, etc. 

= signifies "equivalent to." Thus, Cath. = Catharticus implies that Cath. is 
equivalent to, or stands for, Catharticus ("Cathartic"). 

|| placed after the phrase " Pharmacopoeial name" denotes that the name belongs 
alike to the British and United States Pharmacopoeias. 

An acute accent denotes a primary, a grave a secondary, accent. 

^E^-As a general rule, no marks have been placed on the vowels in cases where 
these would naturally be pronounced correctly without any mark.

Remarks. — r followed immediately by another y, by k, or by %, sounds like n: hence, ay- 
yetov, a -'vessel," should be rendered by angeion or anglon, if Roman letters are used; dyniXos 
('• bent"), by ankylos or ancylos ; !iyx^ (to " choke"), by a?tcfto, etc. Y, though usually considered 
to be equivalent to u, is almost invariably rendered by y, in Latin. See dyKv\os, above given. 
Kis usually replaced in Latin by c, as Kvvdpa or Ktvdfia, cynara or cinara (a kind of "artichoke"). 
As in Latin words of Greek derivation y is sounded like i, and not like u, JH£g= so c should in 
such words be pronounced with its proper Latin sound, — always like s before e, i, and y. 

JKS= A i (in Greek) when changed into Latin, becomes as; and ot, a; as aWioxb, xtJiiops, 
o'tSrifia, oedema, etc. 

/fcg=* H is represented in Greek by *, called the "rough breathing" (spir'itus as'ptr), as in 
vixi, "under," alfia, "blood," etc. All Greek words beginning with a vowel have either the 
rough or smooth breathing (spir'itus le'nis). Compare aWiuxp, "black," atria, "cause," etc. 
the smooth breathing indicates simply tho natural sound of the vowel. 



A, or an before a word beginning with 
a vowel or with h. [a or av.'] A prefix 
in compound words of Greek derivation, 
having a negative or privative force : as, 
tonic, " possessing or imparting tone ;" 
a-tonic, "without tone;" a-cephalous, 
"without a head;" aii-sesthetic, "with- 
out perception;" an-hydroiis, "without 

A is also a French preposition, signi- 
fying "to" or "at," and forming a part 
of certain surgical and- medical phrases, 
as d deux temps, 3, duh to>'°. "At two 
times." Applied to the operation of 
lithotomy, in which the calculus, from 
cert dn causes, cannot be immediately 
extracted, and is therefore let alone till 
during the suppurating stage, when ex- 
traction may be more easily effected. 

AA. A contraction of the Greek 
word ana (wa), signifying, literally, 
"up through" or "throughout;" some- 
times equivalent to "of each." Writ- 
ten in prescriptions after the names of 
several different medicines, to denote an 
equal quantity of each. 

AAA. Abbreviation for Amalgam. 

Ab. A Latin particle signifying 
"from," "off," "away." 

Ab-ac'tus Ven'ter,* or Ven'ter 
Abac'tus.* [From ab, "from," and 
a' go, ac'tum, to "drive," to "force."] 
Literally, a " belly expelled" or emptied 
by forcible means. A term in Medical Ju- 
risprudence for abortion induced by art. 

Ab'a-cus.* [From affa$, u(j<ikos, a 
mathematical table on which lines and 
figures were drawn.] An old name for a 
table used for medicinal preparations. 


Abalienation, ab-al-yen-a'shim. 
[Abaliena'tio, o'nis; from ab, "from," 
and aiie'no, aliena'tum, to " estrange."] 
Formerly used for decay of the whole or 
part of the body ; also, loss or failing of 
the senses or of the mental faculties. 

Abang'a, ab-ang'ga. The name of the 
fruit of a palm-tree growing in the island 
of St. Thomas (West Indies). The seeds 
are considered very useful in diseases of 
the chest. 

Ab-ar-tic-n-la' tion. [ Abarticnla'- 
tio, o'nis; from ofe, "from," and articu- 
la'tio, "articulation."] A kind of ar- 
ticulation admittiug of free motion. See 

Ab-bre'vl-iit-ed. [Abbi*evia'tus; 
from abbre'vio, abbrevia'tum, to "short- 
en."] Shortened, as when the cup is 
shorter than the tube of the flower. 

Ab-bre-vi-ii'iion. [Abbrevia'tio, 
o'nis ; from the same.] A part of a word 
shortened by cutting off one or more of 
its latter syllables. Applied to many 
initial and medial letters, and contrac- 
tions, of medical terms, which will be 
found in their alphabetical order. 

AbcSs. See Abscess. 

Abdoin. Abbreviation for Abdo'men. 

Ab-do'men,* gen. Ab-doni'i-itis.

the seventh to the fourteenth or fifteenth 
year, the period of puberty. 3. Adoles-

of adolescence to about the fiftieth year. 
5. Old Age (senec'tus), which compre- 
hends the declining portion of life.

Firma'ta, the prime or full strength of 
man, — the age from thirty to thirty-five; 
jE'tas Matu'ra, the age of maturity or 
prudence, — the age of fifty.

Literally, "connection by marriage." 
That kind of attraction by which differ- 
ent classes of substances combine to 
form new substances, as in the case of an 
alkali with an acid, forming a salt. As 
marriage unites persons of different or 

opposite sexes, so affinity unites sub- 
stances of different and often opposite 
qualities: e.g. a supporter of combustion 
with a combustible, an alkali with ail 
acid, etc. Affinity is sometimes used, 
but less appropriately, to denote attrac- 
tion in a more general sense. See Af- 
finity of Aggregation. 

Single or Simple Affinity is the 
power by which two elementary bodies 

Elec'tive Affinity denotes the pre- 
ference which one body manifests in 
combining with another rather than 
with a third or fourth, etc. 

Double Elective Affinity occurs 
when two compounds decompose each 
other and two new compounds are 
formed by an exchange of elements. 
Thus, when sulphate of zinc and carbon- 
ate of potassa are mixed, the sulphuric 
acid leaves the zinc and unites with the 
potassa, forming sulphate of potassa, 
while the carbonic acid combines with 
the zinc, producing carbonate of zinc. 

Quies'cent Affinity is that which 
tends to maintain the elements of a 
compound in their present state, prevent- 
ing decomposition. 

Divel'lent Affinity (from divel'lo, 
to "pull apart," to "separate") is that 
which tends to arrange the particles of 
a compound in a new form, producing 
decomposition. In mixing different com- 
pounds, if the sum total of the divellent 
be more powerful than that of the qui- 
escent affinities, decomposition takes 

Disposing Affinity is that which 
promotes the" tendency of bodies to 
combine in a particular way, by pre- 
senting to them a third substance which 
exerts a strong attraction to the com- 
pound they form: when the combina- 
tion has been effected, the third sub- 
stance may be withdrawn. Some writers 
call this tendency to unite the affinity 
of intermedium, or intermediate affinity. 
Berthollet styles it " reciprocal affinity." 

Affin'ity of Ag-gre-ga'tion. A force 
by which two substances tend to com- 
bine and form an aggregate, without 
their properties being changed. An- 
other term for the attraction of cohesion. 

Affin'ity, Chem'i-cal, or Affin'ity 
proper. That property or attraction by

in nature, generally in union with sul- 
phur, or with other metals, or with oxy- 
gen, etc. Though arsenic in its metallio 
state is not dangerous, it is readily con- 
verted into a poisonous oxide, and all 
of its soluble compounds are more or 
less poisonous. Arsenic is also the com- 
mon name for arsenious acid, sometimes 
called white oxide of arsenic, aisen'icvm 
al'bum ("white arsenic"), ratsbane, and

form in which arsenic is found in com- 
merce. The only known antidote for 
this poison is the hydrated sesquioxide 
(or peroxide) of iron, which has been 
found much more efficacious when freshly 
prepared. This substance produces (by 
a transfer of a portion of the oxj'gen 
from the iron to the acid) an insoluble 
and therefore inert subarseniate of the 
protoxide of iron. That this antidote 
may be perfectly successful, it should be 
preceded by the use of emetics, or the 
stomach-pump. See Poisons.

Atom'ic Thc'o-ry. A theory intro- 
duced by Dalton for explaining the laws 
of definite proportions in chemical com- 
binations. It is founded on the sup- 

position that matter consists of ultimate, 
indivisible particles, called atoms, that 
these are of the same size and shape in 
the same body, but differ in weight in 
different bodies, and that bodies com- 
bine in definite proportions with refer- 
ence to those weights, which are hence 
called atomic weights. The main features 
of this theory are briefly stated in the 
following paragraphs. 

In bodies capable of assuming the 
gaseous form, the weight of the atom is 
obtained from the volume : thus, water 
being composed of one volume of oxy- 
gen united with two volumes (or one 
atom) of hydrogen, the relative weights 
will be — oxygen, 8, hydrogen, 1, and 
water, 9. 

In bodies which do not assume the 
gaseous form in their simple state, the 
weight of the atom is deduced from that 
of the compound: the weight of carbon, 
for instance, is obtained from that of 
carbonic acid gas, one volume of which 
weighs twenty-two times as much as 
our standard of unity ; of the twenty- 
two parts, sixteen are hydrogen, leaving 
6 to represent the primary molecule of 

In the case of bodies which are inca- 
pable of assuming a gaseous form, either 
alone or in combination, the weight must 
be obtained by analysis : thus, marble, or 
the carbonate of lime, is found to be 
composed of twenty-two parts of car- 
bonic acid and twenty-eight of lime; 28, 
therefore, represents the atomic weight 
of lime. 

The atomic weights are generally sup- 
posed to be related to one another by 
multiple: hence this law is often called 
the law of multiples, or cf combinations 
in multiple proportion. This will be easily 
seen by referring to the component parts 
of the following substances : — 

Nitrogen. Oxygen. 

Nitrous oxide 14 8 

Nitric oxide 14 16 

Hyponitrous acid 14 24 

Nitrous acid 14 32 

Nitric acid 14 40 

When only one combination of any 
two elementary bodies exists, Dr. Dalton 
assumes that its elements are united, 
atom to atom singly, by what he calls 
binary combinations; if several com- 
pounds can be obtained from the same 
elements, they combine, as he supposes, 
in proportions expressed by some simple 
multiple of the number of atoms, as in 
the following table : — 



Atoms — 
1 of A + 1 of B = 1 of C, binary. 

1 of A + 2 of B = 1 of D, ternary. 

2 of A + I of B = 1 of E, ternary. 

1 of A + 3 of B = 1 of F, quaternary. 

3 of A + 1 of B = 1 of G, quaternary.

Ca'lor Am-I-ma'lis.® Animal ca- 
loric, or animal heat. The term applied 
to the caloric constantly generated in 
the bodies of "living mammalia and birds, 
by means of which the animal is kept at 
nearly a uniform temperature. That of 
the mammalia varies from about 96° to 
106° or 107°,— the Arctic fox, the Arctic 
wolf, and the whale being among those 
that have the highest temperature. The 
animal heat of birds ranges somewhat 
higher than that of the mammalia, the 
temperature of several species being 
above 108°, while that of the Arctic 
finch {Fringilla Arctica), the redbreast 
(Rubecula), and some others is said to 
reach 111°. 

The temperature of those animals even 
which are commonly termed cold-blood- 
ed, is often found to be considerably above 
that of the surrounding medium ; among 
fishes, the most highly organized, such 
as the tunny-fish (Thynnus) and the 
shark, have usually the warmest blood.

"heat."] The matter or cause of the

Sensible or Free Caloric is that 
which produces the sensation of heat or 
affects the thermometer. 

Insensible or Latent Caloric, for- 
merly supposed to be in a state of com- 
bination, is that which passes into bodies 
during a change of form. Thus, it may 
pass into ice at 32°, changing it to water, 
but not increasing the temperature (it has 
hence been termed the caloric of fluidity), 
or into water at 212°, converting it to 
vapor (and termed, in consequence, the 
caloric of evaporation). 

Specific Caloric denotes the unequal 
quantities of caloric required by the 
same quantity of different bodies to heat 
them to a given temperature. Thus, if 
equal weights of water at 40° and mer- 
cury at 160° be mixed together, the re- 
sulting temperature is 45°, showing that, 
computing by weight, water has twenty- 
three times as great a capacity for caloric 
as mercury.

view, the term denotes peculiarities in 
temperature, quality of air, etc., with 
respect to which different countries or 
regions differ from each other in their 
effects upon the health of those who in- 
habit them. Among the various influ- 
ences which tend to promote health or 
produce disease, there is perhaps none 

more deserving the attention of the 
medical student than the peculiarities 
and varieties of climate. But the limits 
of the present volume will permit only a 
few general remarks; for a thorough 
consideration of the subject in all its 
details, the reader i3 referred to more 
extensive and elaborate works. 

In recommending a change of resi- 
dence on account of ill health, the judi- 
cious physician will take into considera- 
tion not only the character of the dis- 
ease, but the peculiarities of the patient's 
constitution. In general terms, it may 
be stated that diseases of the lungs or 
pleura require a mild or warm climate ; 
and fevers, especially when complicated 
with visceral derangement, a cool or 
cold one: yet it will often be found that 
persons laboring under lung-complaints 
are more injured than benefited by a 
warm climate; for, though a mild air 
and unchecked perspiration are very 
decided advantages in themselves, the 
debility resulting from a less bracing 
atmosphere will frequently prove more 
than a counterbalance to those ad- 
vantages. Mountain air, which is gene- 
rally pure, light, and exhilarating, will 
be found beneficial in certain eases, 
while sea air, which is less rarefied and 
less dry, will be better adapted to 
others. The air of a small island com- 
pletely surrounded by a wide expanse of 
sea, like Madeira or the Bermudas, pos- 
sesses the great advantage of having a 
more equable and uniform temperature 
than can ever be found on a continent 
or on any extensive tract of land. It is 
scarcely necessary to remark that the 
purity or impurity of the air must, in an 
especial manner, never be overlooked. 
Yet it is said that the impure air of 
certain districts where tertians are com- 
mon, has been found eminently benefi- 
cial in some forms of pulmonary dis-
